Been away for a few days with overheating issues on a vehicle. Just got back from the range and tried a few things there, verdict is the Starline cases. The Winchester cases shot every 125g Missouri LSWC just fine with no issues at all. The Starline had issues throughout, with cases backing out and ejector sticking again even with faster burning BE powder and tighter neck tension. I have to apologize for some misinformation on bullet hardness and a dyslectic size posting, I'm glad some can read between the lines, thanks. I also load for .38 Special so I get the two crossed up at times.
I did use a Lyman M-Expander in my first loads from last week, so I didn't use it on today's loads thinking maybe it needed more bullet neck tension that some suggested, didn't seem to make a difference. Seems I can use Winchester cases with both bullets and be fine, or I can use Starline cases with just the X-Treme plated and be fine.
There is a lot of great information shared here with this issue and I can't thank you guys enough for the support and encouragement. I'll most likely call Starline in the next few days just to hear what they say. Seems to me their brass is geared towards the Auto market, and why not, that's where the money is.
